Translate Word Problems: Defining Variables in Math

1. Sarah has some apples. Let 'a' represent the number of apples. If she buys 5 more apples, how can we write an equation to show the total number of apples Sarah has now?

• total_apples = a + 5

• total_apples = a - 5

• total_apples = a * 5

• total_apples = a / 5

2. Tom has 't' toy cars. If he gives away 3 toy cars, how can we express the number of toy cars he has left in an equation?

• t - 1

• t + 3

• t - 3

• t / 3

3. A box contains 'b' balls. If 10 balls are added to the box, how can we write an equation to represent the new total number of balls in the box?

• new total = 10 - b

• new total = b * 10

• new total = b + 10

• new total = b - 10

4. Lisa reads 'r' books each month. If she reads 2 more books this month, how can we express the total number of books she has read this month in an equation?

• 2r

• r + 1

• r - 2

• r + 2

5. There are 'd' dogs in a park. If 4 more dogs join them, how can we write an equation to show the total number of dogs in the park now?

• total_dogs = d + 4

• total_dogs = d * 4

• total_dogs = d - 4

• total_dogs = d / 4

6. A baker makes 'c' cupcakes. If he sells 6 cupcakes, how can we express the number of cupcakes left in an equation?

• c - 3

• c - 6

• c / 6

• c + 6

7. Mark has 'm' marbles. If he finds 8 more marbles, how can we write an equation to show the total number of marbles Mark has now?

• total = m * 8

• total = m + 8

• total = m - 8

• total = m / 8

8. A farmer has 'f' fields. If he plants 3 more fields, how can we express the total number of fields he has in an equation?

• f * 3

• f / 3

• f - 3

• f + 3

9. Jenny has 'j' stickers. If she gives away 5 stickers to her friends, how can we write an equation to represent the number of stickers she has left?

• j + 5

• j - 5

• 5 - j

• j - 10

10. A library has 'l' books. If 15 new books are added to the library, how can we express the new total number of books in an equation?

• l - 15

• l + 10

• l + 15

• l * 15
